The HAPI Shorts program is a series of weekly lunch time sessions that you can enjoy in the comfort of your office. Each weekly session will be a 20 to 30-minute presentation followed by questions and answers.
All sessions will be conducted via Zoom. The sessions are FREE but we ask that you registered.
Watch for information about our HAPI Shorts sessions in our monthly newsletter, Facebook page, and website calendar (visit calendar to register).
Follows is a description of the HAPI Shorts sessions:
Title: Intro to Balanced Mix Design
Speaker: Jon M. Young, Hawaii Asphalt Pavement Industry
Balanced Mix Design (BMD) is coming soon to Hawaii. Working together, HDOT and HAPI, moving forward with the implementation.
BMD is an enhanced approach to designing asphalt paving mixtures to achieve a satisfactory balance between rutting resistance and crack resistance. It promises to result in longer lasting asphalt pavements.
This session will cover the basics of BMD and what’s happening in other states.
Title: Intro to Open-Graded Mixes
Speaker: Jon M. Young, Hawaii Asphalt Pavement Industry
An Intro to Open-Graded Mixes will answer the following questions:
– What are open graded mixes?
– Differences from dense graded mixes?
– Where have they been used in Hawaii?
– Where could they be used in the future?
– What’s next?
Title: Intro to Stone Matrix Asphalt (SMA)
Speakers: Jon M. Young, Hawaii Asphalt Paving Industry
This session will introduce Stone Matrix Asphalt (SMA). SMA is a gap-graded hot mix asphalt (HMA) originally developed in Europe to maximize rutting resistance and durability. The mix design goal is to create stone-on-stone contact within the mixture. Since aggregates do not deform as much as asphalt binder under load, this stone-on-stone contact greatly reduces rutting.
Title: Random Sampling Locations
Speaker: Jon M. Young, Hawaii Asphalt Paving Industry
The purpose for sampling is to obtain an uncontaminated and representative sample of the material. Proper sampling is just as important as proper testing. Only a small portion of the total material placed is tested, so samples represent large investments. Samples must be randomly obtained.
This session will review the methodology used by HDOT for randomly determining the sampling location of uncompacted mix and cores from the mat, and location of cores along the longitudinal joint.
Title: Specifying Asphalt Pavement Mixes
Speaker: Jon M. Young, Hawaii Asphalt Paving Industry
It is important that the desired asphalt mix gets specified on the plans and in the specifications. This presentation reviews aggregate gradations and binders used in Hawaii and how they are shown in the plans and specifications.
Future topics being considered include:
– High Friction Surface Treatments
– Design with Construction in Mind
– Modified Binders
– Sustainable Pavements
– Pavement Distresses
Please send any suggestions you have for topics to Jon M. Young at jon@hawaiiasphalt.org.
